GOCE gravity satellite produces maps for geothermal energy development
Going far above and beyond its original mission objectives, results from the GOCE gravity satellite are now being used to produce maps for geothermal energy development.
Spacecraft circling Mercury will crash into planet April 30
After years of orbiting Mercury, NASA's Messenger spacecraft will crash into the planet at the end of this month.
Researchers conduct first direct measurement of gravity's curvature
Theorist suggests a way to test gravitational Casimir attraction
Plants use sixth sense for growth aboard the space station
Although it is arguable as to whether plants have all five human senses – sight, scent, hearing, taste and touch – they do have a unique sense of gravity, which is being tested in space. Researchers with ...
For the first time, astronomers have measured the radius of a black hole
(Phys.org)—The point of no return: In astronomy, it's known as a black hole—a region in space where the pull of gravity is so strong that nothing, not even light, can escape. Black holes that can be billions ...
Quantum steps towards the Big Bang
(Phys.org) —Present-day physics cannot describe what happened in the Big Bang. Quantum theory and the theory of relativity fail in this almost infinitely dense and hot primal state of the universe. Only ...
With neutrons, scientists can now look for dark energy in the lab
It does not always take a huge accelerator to do particle physics: First results from a low energy, table top alterative takes validity of Newtonian gravity down by five orders of magnitude and narrows the ...
Physicists suggest possible existence of other kinds of dark matter
NuSTAR sees rare blurring of black hole light
NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) has captured an extreme and rare event in the regions immediately surrounding a supermassive black hole. A compact source of X-rays that sits near the ...
Astrobiologists claim meteorite carried space algae
New research shows that gravitational fields around black holes might eddy and swirl
Fasten your seatbelts – gravity is about to get bumpy. Of course, if you're flying in the vicinity of a black hole, a bit of extra bumpiness is the least of your worries. But it's still surprising. The ...
'Listening' to black holes form with gravity waves
New technology that breaks the quantum measurement barrier has been developed to detect the gravity waves first predicted by Einstein in 1916.
Gravity measurements confirm subsurface ocean on Enceladus
In 2005, NASA's Cassini spacecraft sent pictures back to Earth depicting an icy Saturnian moon spewing water vapor and ice from fractures, known as "tiger stripes," in its frozen surface. It was big news ...
